Infinity.
A very tough concept for our finite minds to wrap themselves around. But if one were able to go to what you think is the 'Edge of the Universe' . . . I bet one would find still more 'universe' even further out.

And time? This year is 2025 -measured as 2,025 years since the birth of Christ. But, time was marching along long before Christ - and we have the ancient Greeks and Romans and Sumerians etc. etc. as proof of it. There is no beginning or end of time. Time can be warped by the gravitational pull of a black hole. Or by traveling near light speed . . . But Time still IS.

An 'Entropic' Universe? Where all matter and all energy have 'spread out and dissipated' . . . Not gonna happen. Gravity will pull the matter back together again eventually forming the 'Mother of All Black Holes' . . . Till it explodes and everything starts over again.

Whenever one tries to put a 'Finite Limit' to the Universe . . . it stops making sense to me.

Re: “Riddle me this . . How can one go from a 'point in space' with no matter to this 'Big Bang' vomiting all manner of matter components - enough to make a Universe worth of matter . . . ? ? ?”
You should watch the videos fizzy posted. They cover this better than I can.

Penrose believes that before the Big Bang, the universe was in a state of thermal equilibrium. Consequently, things we take for granted did not exist. One of those is the concept of SIZE. If there is no size, then your 'point in space' reference ceases to be an issue.

Ironically, in the distant future when all matter 'evaporates,' the universe will return to a state of thermal equilibrium, and the very, very big universe will be no different from the very, very small pre-universe that spawned the Big Bang.. That sets the stage for a repeat performance... but maybe not an EXACT repeat.
